ELECTRICAL CONNECTIONS

General electrical specifications
• Shunt a power line for the conditioner alone. It must be equipped with an automatic protection device (magneto-
thermic protector switch for industrial loads) at the user's charge, installed on the supply side of the line itself.
• Make sure that the voltage rating of the power line corresponds to the data plate values.
• The power line of all models must be equipped with an appropriately sized protecting conductor (grounding).
• The lines that power the fixed loads of the machine (compressor, fans, etc.) have been sized in compliance with
the current standards governing protection against overloads and short-circuits.
• Remember to connect the conductors from the power source straight to the input terminals of the power isolating
device (refer to the wiring diagrams supplied with the machine).
• The electric panels are equipped with a terminal to connect the protection conductor, identified by the relative mar-
king.
Electrical connections
To allow the conditioner to start, the electrical connections must be made as indicated in the wiring diagrams supplied
with the machine. It is essential to connect the two units to an efficient ground tap. The manufacturer declines
all responsibility for failure to comply with this recommendation.
NOTE: Refer to the wiring diagrams supplied with the machine if any work must be carried out on the elec-
trical system Comply with the specifications given in the following tables for the electrical connections and
connection to the control device.
